To the OP, if you search for my Triac retrofit thread, you'll find how I made a new spindle motor mount to fit a servo, along with some details to rebuild the spindle with new bearings.
Ah, that was your mod, wasnt it? Yes, 3 bolts but when I did the bracket I could only get to 2, as the motor effectively is too big to fit. Your idea is better but needs more work.
